Le lettere come veicolo di diffusione di modelli culturali
Published 2025-01-01“… All’interno dell’epistolario di Ceccarella Minutolo, allestito dalla scrittrice tra la fine degli anni Sessanta e l’inizio degli anni Settanta del Quattrocento, si distingue un gruppo di lettere incentrato sul dibattito intorno ad alcune “quistioni d’amore”. A tale gioco letterario, di evidente ispirazione boccaccesca, sono chiamate a partecipare alcune delle figure più illustri dell’epoca: da Alfonso, duca di Calabria, cioè, a don Ferrando de Guevara, conte di Belcastro, da Francesco Acciapaccia, a Giovanni Albino, riuniti nelle pagine della raccolta in una nobile ed elegante consorteria di adepti d’amore. …”
